Many business buildings have flat roofing, which is a term used to describe roofs with a slope no greater than 10%. While this style is often the most cost-effective and practical for commercial structures, it’s also more prone to damage than sloped roofs. To ensure your flat roof lasts as long as possible, here are some essential maintenance tips to follow. 

How to Care for Flat Commercial Roofing

1. Clear Debris

Keep your flat roof clear of natural debris, such as branches, leaves, and dirt. In addition to blocking drainage systems, these items can create breeding grounds for mold and mildew when wet and cause rotting. Clean the roof at least once a week and after any significant storm.

2. Keep Gutters Clean

Have your gutters cleaned at least twice a year. Otherwise, debris can build up and create blockages, preventing rainwater from properly draining off the roof. This can cause water damage and even lead to foundation problems on the building's ground level.

3. Watch Out for Ponding

Standing water that collects on a flat roof is called ponding. Ponding can cause all types of serious roof damage, including corrosion, rotting, and mold. 

Clogged gutters or rainfall can contribute to ponding. It can also develop over time as a building’s foundation shifts and areas of the roof start to sag, creating low areas where water can pool. If water frequently ponds on your roof, a professional can examine it and install a special drainage system if necessary. 

4. Have Inspections Twice a Year

In addition to your own roof maintenance, schedule biannual inspections with a professional roofing contractor. They’ll clean the roof, examine it for signs of damage, and repair any small issues they find, such as mildew or rot. These regular inspections and small repairs will help prevent larger, more costly problems from occurring.
